Abstract
The invention relates to a preparation process of vitrified color sand, which is used for solving the technical problems of complex process, excessively high cost as well as poor rainwater resistance and easy fading of prepared color sand existing in the color sand preparation method. According to the adopted technical scheme, the vitrified color sand is obtained by coating quartz sand or refractory stone or glass micro-balloons serving as a substrate with color paste and sintering. The key point lies in the color sand sintering process step. Compared with the conventional sintering process, the sintering process step of the preparation process has the advantages that: due to limits on sintering equipment and technology in the prior art, the sintering temperature can only be controlled ina way that surface color paste just reaches initial molten state, so that inorganic pigments in the color paste are independently and lightly attached to the surface layer of the substrate; and in the process, the sintering temperature can be controlled in a way that the color paste and the surface layer of the substrate reach glass fluid state degree at the same time by using self-researched internal heating furnace kiln equipment, so that the color paste in the glass fluid state permeates and is bonded with the molten surface layer of the substrate, and finished color sand is prevented from fading in hundreds of years.
